The Maintenance and Status - Performance screen on both the Base Station
and Subscriber provides WiMAX Statistics. This information can be
used for diagnostics and troubleshooting of the wireless link. The WiMAX
Statistics pane provides packet and byte statistics for both the uplink and
downlink direction.
Note that the term “Downlink” refers to the wireless path from the Base
Station to the Subscriber and the term “Uplink” refers to the Subscriber
to Base Station path. In addition to the packet and byte statistics, each
unit provides packets-per-second and kilobits-per-second metrics in real
time. The Clear WiMAX Statistics button can be clicked to reset the packet
and byte counters and the rate indicators.
